If \( \left(a x^{2}+c\right) y+\left(a^{\prime} x^{2}+c^{\prime}\right)=0 \) and \( x \) is a rational function of \( y \) and \( a c \) is negative, then
(A) \( a c^{\prime}+a^{\prime} c=0 \)
(B) \( \frac{a}{a^{\prime}}=\frac{c}{c^{\prime}} \)
(C) \( a^{2}+c^{2}=a^{2}+c^{2} \)
(D) \( a a^{\prime}+c c^{\prime}=1 \)
